    摘要: The invention relates to high resolution, super wide angle optical assemblies for IR imaging. More particularly, a wide-angle optical assembly for an IR camera is described, comprising a lens system consisting of an object-side lens (2) and an image-side lens (3), and an aperture stop (1) on the object-side of the assembly, wherein: the object-side lens (2) and the image-side lens (3) are positive meniscus lenses; all centers of vertex radii of the lens surfaces are oriented towards the object-side, defining for each lens a concave surface and a convex surface; the thickness (8) of the object-side lens (2) is larger than 0.60 EFL; the thickness (9) of the image-side lens (3) is between 0.30 EFL and 0.70 EFL; 0.95
